I was having a problem where movies (played from a share drive over my LAN) would stop playing and return me back to the summary page at random times. I eventually nailed down the culprit - my router was going bad. I replace the router and all is fine now. But while I was troubleshooting, I had tried various codecs and eventually changed to using VLC as an external program to play my movies. This didn't fix it of course, but now that I solved the problem I went back to using the internal player and using the ffdshow codecs. However, now it won't play a movie at all using the internal player. Instead I get a bunch of weird screen refreshes that seem to be adjusting the screen display sizes and then it goes back to the main menu but at a different display resolution. I don't recall changing anything to do with the display when troubleshooting. When I put it back on the external player it all works fine. I can only assume I changed something that I shouldn't have. Is there a way to return these settings to the default without screwing up the rest of my config? Is there perhaps a list with all of the default configurations that I could look through and choose those that seem to make the most sense? Any other suggestions or magic fixes?
